Question

A store is a 20% of A sale on all merchandise if Maia buys one item and saves $13 what was the original price of her purchase

Answer 1

$65

Explanation:

Maia gets 20% discount and saves $13, that means,

20% of ORIGINAL PRICE is $13, right? Yes!

So, we can setup an equation in x (let original price be x) and solve for the unknown.

20% of what number (x) is 13?

This is what we want. Now remember, 20% converted to decimal is:

20% = 20/100 = 0.20

Now translation the "word equation" above to algebraic equation is:

0.20 * x = 13

Note: "of" means "multiplication" and "is" means "equal to"

Now, let's solve for x (original price):

`0.2*x=13\\x=(13)/(0.2)\\x=65`

The original price is $65
